Look into Voronoi Fracture

Hello everyone, Hope someone has some insight on how to fix this error. While submitting to my local box, to i get this error Not sure what to do or what this means. Any suggestions would be helpful.

Apologies @vicvvsh I missed your post. This is even perfect. So simple and fast to work with. Thank you!

The issue likely stems from how the proxy is exported — it’s being treated as a single mesh without preserving per-component hierarchy. To fix this: In SOPs, ensure each component has a unique path or name attribute (use Name SOP or Attribute Create). In the Redshift Proxy Output SOP, disable "Export as Packed Primitives" to avoid flattening the geometry. In Solaris, when using the Redshift Proxy LOP, set it to "Load as Reference" and confirm that hierarchy is preserved in the Scene Graph Tree. Each component should appear as a separate prim. Once you have separate prims, use Material Library LOP and Material Assign LOP to assign materials to individual components. If the proxy continues to load as a single mesh, consider exporting as USD with proper hierarchy and assigning Redshift materials directly in Solaris for more flexibility. Hope this helps! forward proxy

Hi there, I'm trying to bake vertex colors applied to a high-res mesh into the same mesh but low-res and both have a principled shader applied to it. For now, no matter what I change in the principled shader or in the bake texture rop, the baked image comes out black. White UV island img attached If I just try baking a simple texture based on the high-res uv space, without transferring to the low-res mesh, a shiny white UV island image is created. I checked "Use Point Color' in the principles shader, applied the shader to the mesh, in the "bake texture" rop, I add the UV object, and check the Surface Unlit Base Color (basecolor) and the image is baked white. How can vertex colors can be properly baked in Houdini?

That's exciting! BUF’s in-house 3D app going public is huge—especially if it’s fully procedural. Can’t wait to see how it stacks up against Houdini and Blender!

Does the drive for writing the caches have to be accessible to both machines in a distributed sim? Is it possible to not use a network and just save the caches locally in each machine?

untitled.mp4 sweep basic.hip you answering your own question ... sweep it

VM_Promo.mp4 VEX Manager 1.0 Snippet manager and code editing tool for H20.5+ The VEX Manager is a user-friendly tool for managing and editing VEX code as well as saving notes all within Houdini. It simplifies loading, creating, editing, and organizing VEX expressions, making it essential for artists working with VEX scripts. Download it here https://shirmanor.gumroad.com/l/vex_manager_v1

pop_loop_simple.hip you can do it with a retime untitled.mp4

Hey there. I am trying to do seamless particle loops with the setup attached here. Also tried using the Labs make loop tool but both cause fairly rough transitions. Would be very grateful if someone could a look at this / has a different approach! Thanks a lot. Loop_example.hiplc

just wanna ask if somehow anyone can show the animation of Möbius strip like is it a Möbius strip can be created by sweeping a line (or narrow rectangle) along a twisted circular path with a 180° twist?

Hey I have two buttons in hda's UI one to 'Start paint' and the other 'Done paint' I want each one to toggle the other visibility so they are not shown together, I been digging around with no success can someone point me for a good tip please thank you

okay thats actually the easiest and best way to do it. super simple and effectiv and so obvious.

Amazing, that's it! Thanks so much @hannes603 Really appreciate all the effort both you and @Librarian have gone through here to tackle this one. Goes to show the greatness of the Houdini community. Many thanks.

Hi, changing "Max Points" parm on attribute wrangle will be able to control speed of infection spreading. attribute_spread_v2_animated_01.hipnc

sure you can also do it post solve pretty much the same way .. you only need to accumulate all particles in the solver and remove them afterwards.. otherwise id hase no corrosponding ptnum untitled.mp4 infection_with_changing_point_count_post_solve_simple_improved.hip

something like this Or? Changing position and count @GlennimusPrime

Thanks @Librarian although this example is working post popnet, the number of points is static. The issue still exists of this working on a changing point count sim (post sim, not inside the popnet). That has been the most difficult part of this process that has me stumped.

I don't know the industry standard solution to this. I'm really curious how the big guys handles it. As far as I know alpha for smokeless fire is always a problem if you're working with deep. What we do most of the time is that we use the fire field as smoke and render enough density->alpha that the edges won't be grainy. Of course that will reduce the additive nature of the fire shader to some extent. But you can find a balance/middle ground, where you have enough alpha for proper deep, but the fire still not looking (noticeably) flat. Another approach to do 2 renders. 1 with enough alpha for clean deep, and 1 without alpha, so the fire can be fully additive. Then recolor with the additiv fire. Expensive solution since you're rendering 2 layers, but works. However over the years, I heard some comp guys claim that this alters the deep data in a bad way, and ruin DOF, if they're calculating DOF from deep or something...(?) I never really understood it unfortunately.

Great, this hip helped me

Studio ??? Talk to your manager right away and give these guys a job @hannes603 @konstantin magnus if they need a job.. Find Qiita website . !Advent Houdini 2020! you have Files for Infect and very Nice tricks for making those effects and much more using same Logic . Then(TIP) When you have Full Code that Works in Houdini you can Make anything in chatgpt(reverse and investigete) Now days. Have a nice Day .

Right, got it! Thank you both @Librarian and @hannes603 for the multiple attempts here. Much appreciated! One last thing, what if I wanted to do this as a post-sim infection spread? I'm dealing with pre-cached particles. They have an ID attribute if that helps? I've tried multiple variations of your popvop / pointvop setup but can't seem to get it to work post sim.

Same number of GB, which would you use for large flip & ww simulations: RDIMM or LRDIMM?
